New Injectors! but somethings not right...

I recently had my injectors cleaned and rebuilt. I did everything step by step, took pictures, made my marks, and put everything back together in its place. Now it runs GREAT! but its idling at 1200 rpm warm and it use to run around 800. Am i just used to driving with bad injectors and this is normal or is something wrong?

My car info is in my signature.

It's bound to be running better with clean injectors, so just adjust the idle where you want it.

FSM or haynes manual.

Before adjusting the air bypass screw, tps, or variable resistor, jumper the initial set coupler. Otherwise, the ECU will compensate with BAC air.

If BAC is not available it can't do anything.
